Get an anime/manga's characters

get_media_characters

Read-only

Lists an anime's or manga's characters by role (MAIN, SUPPORTING, BACKGROUND) and returns anime voice actors per dub language. Resolve a title with search_media to get the AniList ID first.

Instructions

List an anime/manga's characters with their role (MAIN/SUPPORTING/BACKGROUND) and, for anime, their voice actors. Use search_media first to resolve a title to its AniList ID. Grouped by role — MAIN first, then SUPPORTING, then BACKGROUND (confirmed live) — and in AniList's own relevance order within each. Voice actors come back in every dub language unless you set voiceActorLanguage; set role to list only one role (e.g. just the MAIN cast).

Input Schema

Name	Required	Description
`id`	Yes	AniList ID.
`page`	No	Page number for pagination. AniList's paginated connections (search results, a title's characters/staff/reviews, activity feeds, forum comments) reject a page whose page × perPage exceeds ~5000 entries with an upstream error, so paging that deep fails rather than returning more results.
`role`	No	Only return characters with this role. Omit for every role.
`type`	Yes	Whether `id` refers to anime or manga.
`perPage`	No	Results per page (max 25, AniList's own ceiling — it silently clamps anything higher).
`voiceActorLanguage`	No	Only return voice actors for this dub language (e.g. JAPANESE for the original cast, ENGLISH for the English dub). Omit for every language — AniList then returns all dubs per character (8 for most of Attack on Titan's main cast), which multiplies the response size.

Output Schema

Name	Required	Description	Default
`characters`	Yes

A4.6/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Goes well beyond the readOnly/openWorld annotations: discloses result ordering (MAIN, then SUPPORTING, then BACKGROUND, relevance order within each) and the multiplicative response-size effect of returning all dub languages unless filtered. This is exactly the kind of behavior an agent can't infer from structured fields.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Front-loaded with purpose, then guidance, then ordering and filter notes, with no filler sentences. It is slightly dense in a single paragraph with multiple em-dash asides, but every sentence carries an operational fact.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With a 100%-covered schema and an output schema, the description only needs to supply routing, ordering, and response-size behavior — and it does all three. Nothing an agent needs to call this correctly is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3; the description still adds meaning by explaining the downstream effect of `voiceActorLanguage` (all dubs returned by default, response bloat) and `role` (single-role filtering). Marginal but real value over the schema text.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('List an anime/manga's characters') and immediately enumerates the payload fields (role, voice actors). It is clearly distinguishable from siblings like get_character or get_media_staff.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes the agent: 'Use search_media first to resolve a title to its AniList ID.' It also gives actionable conditions for optional filters (set `voiceActorLanguage` to narrow dubs, set `role` for one role). It doesn't name when to prefer get_character for a single character, but the primary prerequisite is covered.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
